SC16C850SV - 1.8 V的单通道UART，20 Mbit/s（最快），带有128字节FIFO、红外IrDA以及XScale VLIO总线接口

Overview

The SC16C850SV is a 1.8 V, low power single channel Universal Asynchronous Receiver and Transmitter UART used for serial data communications. Its principal function is to convert parallel data into serial data and vice versa. The UART can handle serial data rates up to 20 Mbit/s 4× sampling rate. SC16C850SV can be programmed to operate in extended mode where additional advanced UART features are available. The SC16C850SV family UART provides enhanced UART functions with 128-byte FIFOs, modem control interface and IrDA encoder/decoder. On-board status registers provide the user with error indications and operational status. System interrupts and modem control features may be tailored by software to meet specific user requirements. An internal loopback capability allows on-board diagnostics. Independent programmable baud rate generators are provided to select transmit and receive baud rates.

The SC16C850SV with Intel XScale processor VLIO interface operates at 1.8 V and is available in the HVQFN32 package.
